A Behavioral Account of the Labor Market: The Role of Fairness Concerns

In this paper, we argue that important labor market phenomena can be better understood if one takes (a) the inherent incompleteness and relational nature of most employment contracts and (b) the existence of reference-dependent fairness concerns among a substantial share of the population into account. Theory shows and experiments confirm that, even if fairness concerns were to exert only weak effects in one-shot interactions, repeated interactions greatly magnify the relevance of such concerns on economic outcomes. We also review evidence from laboratory and field experiments examining the role of wages and fairness on effort, derive predictions from our approach for entry-level wages and incumbent workers' wages, confront these predictions with the evidence, and show that reference-dependent fairness concerns may have important consequences for the effects of economic policies such as minimum wage laws.

Two days of hypoxic exposure increased ventilation without affecting performance.

The aim of this study was to test the short-term effects of using hypoxic rooms before a simulated running event. Thirteen subjects (29 +/- 4 years) lived in a hypoxic dormitory (1,800 m) for either 2 nights (n = 6) or 2 days + nights (n = 7) before performing a 1,500-m treadmill test. Performance, expired gases, and muscle electrical activity were recorded and compared with a control session performed 1 week before or after the altitude session (random order). Arterial blood samples were collected before and after altitude exposure. Arterial pH and hemoglobin concentration increased (p < 0.05) and PCO2 decreased (p < 0.05) upon exiting the room. However, these parameters returned (p < 0.05) to basal levels within a few hours. During exercise, mean ventilation (VE) was higher (p < 0.05) after 2 nights or days + nights of moderate altitude exposure (113.0 +/- 27.2 L.min) than in the control run (108.6 +/- 27.8 L.min), without any modification in performance (360 +/- 45 vs. 360 +/- 42 seconds, respectively) or muscle electrical activity. This elevated VE during the run after the hypoxic exposure was probably because of the subsistence effects of the hypoxic ventilatory response. However, from a practical point of view, although the use of a normobaric simulating altitude chamber exposure induced some hematological adaptations, these disappeared within a few hours and failed to provide any benefit during the subsequent 1,500-m run.

Effect of white-matter lesions on the risk of periprocedural stroke after carotid artery stenting versus endarterectomy in the International Carotid Stenting Study (ICSS): a prespecified analysis of data from a randomised trial.

BACKGROUND: Findings from randomised trials have shown a higher early risk of stroke after carotid artery stenting than after carotid endarterectomy. We assessed whether white-matter lesions affect the perioperative risk of stroke in patients treated with carotid artery stenting versus carotid endarterectomy. METHODS: Patients with symptomatic carotid artery stenosis included in the International Carotid Stenting Study (ICSS) were randomly allocated to receive carotid artery stenting or carotid endarterectomy. Copies of baseline brain imaging were analysed by two investigators, who were masked to treatment, for the severity of white-matter lesions using the age-related white-matter changes (ARWMC) score. Randomisation was done with a computer-generated sequence (1:1). Patients were divided into two groups using the median ARWMC. We analysed the risk of stroke within 30 days of revascularisation using a per-protocol analysis. ICSS is registered with controlled-trials.com, number ISRCTN 25337470. FINDINGS: 1036 patients (536 randomly allocated to carotid artery stenting, 500 to carotid endarterectomy) had baseline imaging available. Median ARWMC score was 7, and patients were dichotomised into those with a score of 7 or more and those with a score of less than 7. In patients treated with carotid artery stenting, those with an ARWMC score of 7 or more had an increased risk of stroke compared with those with a score of less than 7 (HR for any stroke 2·76, 95% CI 1·17-6·51; p=0·021; HR for non-disabling stroke 3·00, 1·10-8·36; p=0·031), but we did not see a similar association in patients treated with carotid endarterectomy (HR for any stroke 1·18, 0·40-3·55; p=0·76; HR for disabling or fatal stroke 1·41, 0·38-5·26; p=0·607). Carotid artery stenting was associated with a higher risk of stroke compared with carotid endarterectomy in patients with an ARWMC score of 7 or more (HR for any stroke 2·98, 1·29-6·93; p=0·011; HR for non-disabling stroke 6·34, 1·45-27·71; p=0·014), but there was no risk difference in patients with an ARWMC score of less than 7. INTERPRETATION: The presence of white-matter lesions on brain imaging should be taken into account when selecting patients for carotid revascularisation. Carotid artery stenting should be avoided in patients with more extensive white-matter lesions, but might be an acceptable alternative to carotid endarterectomy in patients with less extensive lesions.

Mutations in DNAH5 account for only 15% of a non-preselected cohort of patients with primary ciliary dyskinesia.

BACKGROUND: Primary ciliary dyskinesia (PCD) is characterised by recurrent infections of the upper respiratory airways (nose, bronchi, and frontal sinuses) and randomisation of left-right body asymmetry. To date, PCD is mainly described with autosomal recessive inheritance and mutations have been found in five genes: the dynein arm protein subunits DNAI1, DNAH5 and DNAH11, the kinase TXNDC3, and the X-linked retinitis pigmentosa GTPase regulator RPGR. METHODS: We screened 89 unrelated individuals with PCD for mutations in the coding and splice site regions of the gene DNAH5 by denaturing high performance liquid chromatography (DHPLC) and sequencing. Patients were mainly of European origin and were recruited without any phenotypic preselection. RESULTS: We identified 18 novel (nonsense, splicing, small deletion and missense) and six previously described mutations. Interestingly, these DNAH5 mutations were mainly associated with outer + inner dyneins arm ultrastructural defects (50%). CONCLUSION: Overall, mutations on both alleles of DNAH5 were identified in 15% of our clinically heterogeneous cohort of patients. Although genetic alterations remain to be identified in most patients, DNAH5 is to date the main PCD gene.

A consistent extension of the local spin density approximation to account for quantum dot mass and dielectric mismatches

A consistent extension of local spin density approximation (LSDA) to account for mass and dielectric mismatches in nanocrystals is presented. The extension accounting for variable effective mass is exact. Illustrative comparisons with available configuration interaction calculations show that the approach is also very reliable when it comes to account for dielectric mismatches. The modified LSDA is as fast and computationally low demanding as LSDA. Therefore, it is a tool suitable to study large particle systems in inhomogeneous media without much effort.

Premier cas de néphropathie epidémique endémique en Suisse [First case of nephropathia epidemica acquired in Switzerland]

A 43 year healthy old man complains of fever with abdominal pain, vomiting, diarrhoea, followed by the development of thrombocytopenia and acute renal failure. The laboratory tests show the presence of Hantavirus specific IgM and IgG which is confirmed by a specific test revealing Puumala serotype as responsible. The patient received a symptomatic treatment with a favourable evolution allowing discharge about ten days after the beginning of symptoms. Hantavirus are transmitted by rodents, and this patient has certainly been infected in Switzerland in the absence of travel abroad during the incubation period. This means that when confronted in Switzerland with an acute nephritis of unknown origin, a diagnosis of nephropathia epidemica must be taken into account.

Traitement de la dépression résistante par l'association citalopram-lithium. Méthodologie d'une étude multicentrique en double aveugle et résultats préliminaires [Treatment of resistant depression with the citalopram-lithium combination. Methodology of a double-blind multicenter study and preliminary results].

Citalopram, a new bicyclic antidepressant, is the most selective serotonin reuptake inhibitor. In a number of double-blind controlled studies, citalopram was compared to placebo and to known tricyclic antidepressants. These studies have shown their efficacy and good safety. The inefficacy of a psychotropic treatment in at least 20% of depressives has led a number of authors to propose original drug combinations and associations, like antidepressant/lithium (Li), antidepressant/sleep deprivation (agrypnia), antidepressant/ECT, or antidepressant/LT3. The aim of this investigation is to evaluate the clinical effectiveness and safety of a combined citalopram/lithium treatment in therapy-resistant patients, taking account of serotonergic functions, as tested by the fenfluramine/prolactin test, and of drug pharmacokinetics and pharmacogenetics of metabolism. DESIGN OF THE STUDY: A washout period of 3 days before initiating the treatment is included. After an open treatment phase of 28 days (D) with citalopram (20 mg D1-D3; 40 mg D4-D14; 40 or 60 mg D15-D28; concomitant medication allowed: chloral, chlorazepate), the nonresponding patients [less than 50% improvement in the total score on the 21 item-Hamilton Depression Rating Scale (HDRS)] are selected and treated with or without Li (randomized in double-blind conditions: citalopram/Li or citalopram/placebo) during the treatment (D29-D35). Thereafter, all patients included in the double-blind phase subsequently receive an open treatment with citalopram/Li for 7 days (D36-D42). The hypothesis of a relationship between serotoninergic functions in patients using the fenfluramine/prolactin test (D1) and the clinical response to citalopram (and Li) is assessed. Moreover, it is evaluated whether the pharmacogenetic status of the patients, as determined by the mephenytoin/dextromethorphan test (D0-D28), is related to the metabolism of fenfluramine and citalopram, and also to the clinical response. CLINICAL ASSESSMENT: Patients with a diagnosis of major depressive disorders according to DSM III are submitted to a clinical assessment of D1, D7, D14, D28, D35, D42: HDRS, CGI (clinical global impression), VAS (visual analog scales for self-rating of depression), HDRS (Hamilton depression rating scale, 21 items), UKU (side effects scale), and to clinical laboratory examens, as well as ECG, control of weight, pulse, blood pressure at D1, D28, D35. Fenfluramine/prolactin test: A butterfly needle is inserted in a forearm vein at 7 h 45 and is kept patent with liquemine. Samples for plasma prolactin, and d- and l-fenfluramine determinations are drawn at 8 h 15 (base line). Patients are given 60 mg fenfluramine (as a racemate) at 8 h 30. Kinetic points are determined at 9 h 30, 10 h 30, 11 h 30, 12 h 30, 13 h 30. Plasma levels of d- and l-fenfluramine are determined by gas chromatography and prolactin by IRNA. Mephenytoin/dextromethorphan test: Patients empty their bladders before the test; they are then given 25 mg dextropethorphan and 100 mg mephenytoin (as a racemate) at 8 h 00. They collect all urines during the following 8 hours. The metabolic ratio is determined by gas chromatography (metabolic ratio dextromethorphan/dextrorphan greater than 0.3 = PM (poor metabolizer); mephenytoin/4-OH-mephenytoin greater than 5.6, or mephenytoin S/R greater than 0.8 = PM). Citalopram plasma levels: Plasma levels of citalopram, desmethylcitalopram and didesmethylcitalopram are determined by gas chromatography--mass spectrometry. RESULTS OF THE PILOT STUDY. The investigation has been preceded by a pilot study including 14 patients, using the abovementioned protocol, except that all nonresponders were medicated with citalopram/Li on D28 to D42. The mean total score (n = 14) on the 21 item Hamilton scale was significantly reduced after the treatment, ie from 26.93 +/- 5.80 on D1 to 8.57 +/- 6.90 on D35 (p less than 0.001). A similar patCitalopram, a new bicyclic antidepressant, is the most selective serotonin reu

Protracted treatment with MDMA induces heteromeric nicotinic receptor up-regulation in rat brain: an autoradiography study.

Previous studies indicate that 3,4-methylenedioxy-methamphetamine (MDMA, ecstasy) can induce heteromeric nicotinic acetylcholine receptor (nAChR, mainly of α4β2 subtype) up-regulation. In this study we treated Sprague-Dawley rats twice-daily for 10 days with either saline or MDMA (7 mg/kg) and killed them on day 11 to perform [125I]epibatidine binding autoradiograms on serial coronal slices. Results showed significant increases in nAChR density in the substantia nigra, ventral tegmental area, nucleus accumbens, olfactory tubercle, anterior caudate-putamen, somatosensory cortex, motor cortex, auditory cortex, retrosplenial cortex, laterodorsal thalamus nuclei, amygdala, postsubiculum and pontine nuclei. These increases ranged from 3% (retrosplenial cortex) to 30 and 33% (amygdala and substantia nigra). No increased α4 subunit immunoreactivity was found in up-regulated areas compared with saline-treated rats, suggesting a post-translational mechanism as occurs with nicotine. The percentage of up-regulation correlated positively with the density of serotonin transporters, according to the serotonergic profile of MDMA. The heteromeric nAChR increase in concrete areas could account, at least in part, for the reinforcing, sensitizing and psychiatric disorders observed after long-term treatment with MDMA.

Incidence of Infectious Complications in Kidney Transplant Recipients Receiving Induction with Basiliximab, Thymoglobulin or Both

Background: The possible additional risk of infection in patients receiving induction with both basiliximab (Ba) and thymoglobulin (Th) is unclear. We assessed the 1-year incidence of infectious complications in 3 groups of kidney transplant recipients according to the type of induction therapy received.Methods: We compared the incidence of infection at 1 year in 3 groups of patients at our institution: fi rst transplant recipients received Ba 20mg at days 0 and 4 (Group Ba); in case of retransplantation or if PRA was >20% patients received Th 1 mg/kg for 3-5 days (Group Th); in case of delayed graft function (DGF), Ba was discontinued and Th was initiated (Group Ba+Th) or prolonged in Group Th. Kaplan-Meier curves were used to calculate the incidence of infection. A Cox analysis was used to identify risk factors for the development of infection.Results: Over 5 years, 170 consecutive kidney transplant recipients were performed:n=113 in Group Ba, n=39 in Group Th and n=18 in Group Ba+Th. As expected, more patients in Group Th received a second transplant (p<0.001). No differences in CMV serostatus were observed between groups (p=0.9). Incidences of CMV infection, CMV disease, BK viremia, BK nephropathy and urinary tract infection (UTI) is shown in Table 1. Table 1 Group Ba (n=113) Group Th (n=38) Group Ba+Th (n=18) CMV infection 31 (27%) 20 (51%) 8 (44%) CMV disease 7 (6%) 4 (10%) 0 BK viremia 11 (8%) 5 (13%) 4 (22%) BK nephropathy 5 (4%) 1 (2%) 2 (11%) UTI 43 (38%) 23 (59%) 6 (33%) Incidences of infection according to type of induction In a multivariate model taking into account CMV serostatus, age, pretransplant dialysis, type of organ transplanted, number of transplants and type of induction, Group Ba carried a lower risk of CMV infection (OR 0.45, p=0.006), and UTI (OR=0.6, p=0.05), but there were no differences in CMV disease (p=0.38). There was a trend towards higher incidence of BK viremia, but not nephropathy in Group Ba+Th (OR 2.2, p=0.23). There were no signifi cant differences in kidney function or graft loss at 1 year between groups.Conclusion: By multivariate analysis, we observed a lower risk of CMV infection andUTI in patients receiving Ba. The group Ba+Th had a similar risk for infection than the group receiving Th alone. Larger studies are needed to clarify whether combining Ba+Th in the setting of DGF may increase the risk of infectious complications, in particular BK infection.

Development of aBuyer-Supplier Relationship: Case Study of Radical Shifts in Key Account Relationships

Tämän tutkimuksen tavoitteena oli tutkia ja selvittää monimutkaisia myyjän ja toimittajan välisiä liikesuhteita; miten ne kehittyvät ja millaisia prosesseja ne käyvät läpi, jos avainasiakassuhde on vaikeuksissa. Tavoitteena oli myös löytää syitä miksi ostokäyttäytyminen on muuttunut, onko se maailman- laajuinen ilmiö vai onko kyse vain yksittäisestä tapauksesta paperiteolli-suudessa. Lisäksi tavoitteena oli selvittää mitkä ovat alkusysäyksiä avain-asiakassuhteen murrostilaan. Tutkimuksen lähestymistapa on kvalitatiivinen tapaustutkimus. Tutkimuksen ensisijainen empiirinen aineisto on kerätty haastattelemalla UPM-Kymmenen johtoa, paperin osto-organisaation ostojohtajaa X ja asiakas Y:n entistä osto-johtajaa. Työ ei ole salainen. Tämän takia asiakkaiden nimiä ei voida julkaista, koska UPM-Kymmene vaati, että työ ei saa sisältää mitään informaatiota, josta lukija voi tunnistaa asiakas X:n tai Y:n. Johtopäätöksenä voidaan suosittaa toimittajan tarkkailevan ja ymmärtävän mahdollisia alkusysäyksiä ja varoitussignaaleja ehkäistäkseen tulevaisuuden murrostiloja liikesuhteissaan ja hallita paremmin avainasiakkaitaan.Pääasialliset alkusysäykset ovat vähentynyt avoin kommunikaatio, ostajan radikaalit säästöt, vähentynyt informaation vaihto ja ostajan johdon vaihtuminen, koska se luo epävarmuutta toimittajaan kuten myös ostajaan.
